This SnO2-loaded organic–inorganic hybrid structure effectively addresses the issue of hydrophilic-material loss in traditional organic polymers under high-humidity conditions, notably enhancing the stability of g-C3N4. The introduction of Ov considerably enhances water molecule–adsorption and electron-transfer capabilities, providing more adsorption sites for water molecules and facilitating their decomposition and proton conduction, thereby greatly enhancing the sensor's sensitivity and response speed. The reduction in water contact angle further increases the material's hydrophilicity, enhancing the sensor's response performance. The incorporation of –NHx groups effectively shortens the response and recovery times. The SnO2/g-C3N4 sensor exhibits remarkable stability, low response/recovery times (9/6 s), and low hysteresis (2.3%) across a relative humidity range of 11%–95%, hence demonstrating its great potential for practical applications.

The SC/4YSZ thick thermal barrier coatings (TTBCs) are processed using atmospheric plasma spraying (APS). The experimental results reveal that the SC/4YSZ system displays superior thermal shock resistance in comparison to 4YSZ coatings. Specifically, the SC/4YSZ system can withstand 23 consecutive thermal cycles at a surface temperature up to 1750 °C, while the 4YSZ TTBCs fail after only one cycle. The enhanced durability of the SC/4YSZ system is attributed to the superelasticity of the SC coating, which undergoes a stress-induced reversible martensitic transformation, absorbing strain energy as heat. This capability improves with each thermal cycle as the depth of the martensitic phase transformation region increases during thermal cycling.
